One of our users is having an issue with exporting dxfs from Creo drawings...specifically with curved edges (like rounds) appearing as jagged straight lines. On the model the jagged edges are visible but this is rectified by changing the relative accuracy from 0.0012 to 0.0001 (Is this increasing or decreasing the accuracy?) so I appreciate it is a size thing in terms of the model.
So he fully regenerates the model and drawing and then exports the dxf again....when he opens the dxf in AutoCAD it has the jagged edges. If he opens it in another product called DraftSight the edges are smooth. That in itself is odd.
The problem we have is that he sends the dxf to Sigmanest (without opening it in either AutoCAD or Draftsight) for nesting on a piece of sheetmetal. When the part is physically cut it has jagged edges not smooth.
I'm at a loss as to know which program is causing the problem...he is the only one out of 35 users with this issue.
Anybody got any ideas?
Try making a part that is as simple as possible - like a square with a single radius that exhibits the difference and export that to DXF from a 'good' computer and the 'bad' computer.
Then open each one with a text editor to see if there is a difference in the header (will tell what version) or in the geometry.
With luck the geometry is identical and it's the version that's a problem. If both are different there are other settings to deal with.
Autodesk hosts DXF format information http://www.autodesk.com/techpubs/autocad/acad2000/dxf/entities_section.htmto help understand what the file contents means. It's not difficult, just tedious. Hence the suggestion for a really simple part.
